Having an issue with a mixed GPU folding system I put together today, I tested all the components independently and run fine. The system runs fine at first when using the microsoft WDM or vesa drivers, but after installing the nvidia drivers 195.X, or attempting to change the resolution on either screen the system BSOD's complaining about nvlddmkm.sys, on subsequent reboots the system will hard lock on login to windows 7, until I go into safe mode and remove the displayer driver. If I remove either card the system runs / folds fine....

I pulled the 8800GT again, and well doing so have noticed that cards are unusually hot, touching the plastic housing around the fan/heatsink assembly was more then enough to burn my fingers. Yet both fans were running.
